The Ballad of Miss Kitty and Smoochy the Pooch

Sometimes, the universe lines things up just right. A cat loses her kittens; an indifferent doggy gives birth to a litter of pups. (You see where this is going). Miss Kitty adopts puppies, people worry puppies might be confused--but they're not. Smoochy's free to party, and everyone lives happily ever after.
